The entire private market in one API
Secondary Market Data
Live order book, trade history, and order history across the most actively traded private companies — plus our proprietary MarketPrice estimate built from real flow.
Funding Rounds
Round-by-round amounts, valuations, participants, and source citations. Pull a single round, a company history, or the global updates feed as new rounds are confirmed.
Company Firmographics
Company profiles, COI filings, stock splits, fund marks from SEC filings, news with sentiment, and quarterly market summaries.
Investor Data
Investor participation across funding rounds — the funds, firms, and individuals on the cap tables of every covered company.
Comps & Indices
Comparable-company performance and composite index timeseries, sliced by sector and vertical for benchmarking late-stage marks.
Company Signals
Revenue, headcount changes, hiring trends, customer wins, and product milestones — the operating signals that move private-market valuations between rounds.
The Caplight MCP Server
Connect Claude, Cursor, or any MCP-aware agent to Caplight's live pricing, rounds, investors, and signals — no integration to maintain.
Claude
Add the Caplight MCP server to Claude desktop or claude.ai. Ask in plain English — Claude pulls live MarketPrice quotes, recent funding rounds, cap-table investors, and trade prints directly from Caplight, then reasons over the result in the same conversation.
AI agentic workflows
Drop Caplight into LangGraph, CrewAI, OpenAI Agents, or any MCP-aware runtime. Multi-step research agents can pull pricing, screen comps, and enrich CRM records at runtime — without bespoke connectors per data source.
Embed Caplight on your platform
The embed API renders live MarketPrice quotes, fund marks, and order activity inside your own application — fully themeable, kept fresh by Caplight, and installable in a single line of code.
- One-line install — no backend integration required
- Customizable theme, layout, and which datasets to surface
- Auth, refresh, and entitlements handled by Caplight
